By the time J.H. Todd published his study of Irish illuminations, the techniques of
chromolithography had much improved, as can be seen from this magnificent reproduction
of the Chi-Rho page of the Book of Kells. To be sure, the work was done by one
of the best firms specializing in color reproduction at that time: Storch & Kramer
of Berlin (Germany) -- working from a copy by Margaret Stokes.

When it comes to distinguishing the detail of the interlaced ornament, this technique
seems more effective than the realistic approach of the full facsimile of theBook of Kells.
